What diameter and thickness rotors are on the car now?

The .81 thick Dynalite series 11 inch rotors can be increased to the 12.19 inch.
Not too long ago I sold what was needed including the larger rotors, new caliper brackets, and rotor adapters.

If they already are the 12.19 inch I believe you are as big as you can go. At that point the 13 inch rotors are wider (1.13 wide?) The same can be said for 14 inch which are usually 1.25 wide.
